EDIT: my LCD screen is probably failing. After the classic "turning off and back on again" made the UV test actually show. So we'll see if that will actually work for now. I've had the printer for like 3.5 months now.
I'm having some problems for the first time since I bought it
I'm using Anycubic gray, 90 secs with 6 base layers, and 6 seconds normal exposure time. I'll get a job done, and then the next job fails.
Does there need to be a cool down time between jobs? Inside the printer was a bit warm.
I did have to reset the z=0 once because for some reason it wasn't going all the way down. I hope something isn't wrong with my printer.
I've had several jobs within the past couple days end up like the picture below.

I had something similar and what I discovered was that a job would complete but then the next would fail because of resin left on the fep from the successful one. Not 100% cured but enough to make it fail.
Turned out the LCD was failing and was Curing a 'shadow' on the fep between layers when it should have been dark.
Changed the screen and it was fixed, improvement in print quality too!

That might be it. I've also emptied the vat and the fep looked fine. This is the exposure test

I think my screen failed. I turned it off and back on again and then it was acting normal...? That's so weird

mine looked fine on the exposure test but it was clesrly letting UV through when it shouldn't have.

Hmmm.. what's weird for me is it wasn't doing any uv light and then after turning it off and back on, it showed up again. If this doesn't print then I'll have to get a new screen for sure

If your screen is old (mine was 14 months old with no dead areas) you may be best doing it anyway, the improvement in print quality very noticeable!

It's only 3.5 months old, as I got it for a Christmas gift for myself.

Hmmmm, there is no saying how long each one lasts. I've heard of people having them degrade in that time though. I was just lucky.

Dang. Well thanks for your advice. We'll see what happens
